A flow-view based dynamic QoS guarantee mechanism

With the increasingly rich Internet services, the problem has been more important and vital that the network is unable to meet the diverse needs of network services. In this paper, a flow-view based dynamic QoS guaranteed mechanism (FDQoS) is proposed to realize the QoS support for new services, and to guarantee the network QoS dynamically according to the requirements of data flows. The basic idea is to provide QoS guarantee for the network flows of the same type in the intensively distributed interval calculated based on the flow distribution, namely the flow view. Network resources can be allocated rationally and flows can get QoS guarantee according to their needs. Simulation results show that the FDQoS can dynamically adapt to changing network environment and provide QoS guarantee for different types of network flows.
